Sometimes the best ideas are the ones you hear about after it’s too late.

Case in point: To relieve Los Angeles motorists who will be suffering in the midst of Carmegeddon as the Interstate 405 freeway shuts down this weekend, JetBlue airlines offered flights between Burbank and Long Beach for $4. Granted the flight would be 20 minutes, but the drive on Saturday would likely be more than an hour — if you can figure out a route.
